SPECIFICATION `forming part of vLettersl/Patent No. 780,743, datedJanuary 24, 1905. Application filed October 13, 1904:.r Serial No.228,271.

vTo @ZZ whom it may con/cern.' Y

Be it known that I, SAMUEL J. GLOKEY, a citi- Zen of the United Statesof America, residing at Washington, in the county of I/Vashington andState of Pennsylvania, have invented certain new and useful Improvementsin Wrenches, of which the following is a specication, reference beinghad therein to the accompanying drawings.

This invention has relation to certain new and useful improvementsv inwrenches, and more particularly vto that type commonly known as amonkey-wrench.

This invention has for its object the provision of a novel form ofwrench which may be readily used as a pipe-wrench, and. I have providednovel means whereby said wrench may be quickly changed to a pipe-wrench,also means whereby the sliding jaw of said wrench may be quicklyadjusted to any desired position and then more finely adjusted to placethe sliding jaw in a more firm engagement with an object.

Briefly described, my improved wrench comprises a shank having a handlesecured upon its onev end and a detachable jaw upon its other end. Uponthis shank is slidingly mounted an adjustable jaw having a pivotedhandle which is adapted to engage with a toothed bar adj'ustablymounted'within the shank of the wrench.

The above construction will be hereinafter more Jfully described, andspecifically pointed out in the claims.

In describingV the invention in detail reference is had to theaccompanying drawings, forming a part of this application, and whereinlike numerals of reference indicate. like parts throughout the severalviews, in which-n Figure 1 is a side elevation of my improved wrench.Fig. 2 is a vertical sectional view of the same. Fig. 3 is an edge viewof the wrench., the jaws thereof being shown in vertical section. Fig. 4is aperspective view of a handle carried by the adjustable jaw. Fig. 5is an underneath perspective view of a modified form of adjustable jawdetached from the shank and from the handle. Fig. 6 is an underneathperspective view of a modified form of stationary jaw detached from theshank.

To put my invention into practice, I em-V ploy a-shank 1,'having atapering screwthreaded end 2, upon which the handle 3 is secured bya nut4C. The upper end of the shankis 'providedwith an aperture 5, and uponthis endis secured by a pin 6 a jaw 7, which upon its under face isprovidedwith a recess 8, with which communicate apertures 9 9, wherebythe pin 6 may be placed in said 'apertures and the aperture 5 to securethe jaw upon the upper end of the shank. The shank upon its one edge iscut away, as indicated at 10, and the upper'edge of the cutaway portionisprovided with a recess, 11 and the rear wall of the cut-away portionnear the lower end is provided with a recess 12. In said` cut-awayportion is mounted a toothed bar 14, which is held in said recess by apin 15, which protrudes into the recess 11, and by a screw 16, which ismounted in the cut-away portion between the lower end of the toothed barand the base of said cut-away portion. The screw 16 is provided with aknurled nut 17, which is fixed on the screw andv which is adapted to liewithin the recess 12 of said cutaway portion. The shank is further outaway, as indicated at 18, and secured upon said c utaway portion byscrews 19 is a retaining guide-plate 20, `said plate extending upwardlya suicient distance to bear against the toothed bar 14 and retainthesame in the cut-away portion of the shank.

Upon the shank 1 is mounted a sliding' jaw 21, which upon its under faceis provided with a depending lug 22, and to this lug is pivotallyconnected by a pin 23 the handle 24. The said handle near its pivotedend and upon its inner face is provided With a tooth 25. This tooth isnormally adaptedto engage two of' the teeth of the toothed bar 14, andin order that said tooth 25 may be held in engagement with. the toothedbar I have provided the slot 26 in the handle 8, whereby the handle 24may be drawn into engagement with the handle 3 and retained therein bythe hand of the person manipulating the wrench.

- surfaces.

In Figs. 5 and 6 of the drawings I have illustrated detachable jawswhich are similar in all respects to the jaws 7 and 21, with theexception that said jaws are provided with the serrated concave surfaces27 and Q8, and these jaws are employed when the wrench is to be used asa pipe-wrench or for grippingcurved By removing the jaw 7 and thenremoving the jaw 2l from the shank of the wrench these auxiliary jawsmay be placed upon the shank to provide a pipe-wrench. By theconstruction of the adjustable jaw it will be seen that the same may bequickly adjusted upon the shank and held in engagement with any desiredobject. Should the teeth of the bar 14 not be suiiicient to permit of aperfect engagement of the adjustable jaw with the object, the knurlednut 17 is rotated to 'raise said toothed bar and the adjustable jaw intofurther engagement with said object.

From the foregoing' description it will be observed that I haveconstructed my improved wrench upon as simple lines as possible and thatthe wrench may be quickly adjusted to grip a desired object, and while Ihave herein shown the preferred form of constructing the wrench it isobvious that various changes may be made in the details of constructionwithout departing from the general spirit of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. A wrench comprising a'recessed shank, a jaw rigidly attached to saidshank, a slotted handle attached to the shank, a toothed bar mounted inthe recess oi lthe shank, an adjusting-screw mounted in the recess inthe shank below said toothed bar, a slidable jaw mounted on the shank, alever pivotally attached to said slidable jaw, the said lever beingprovided with a tooth adapted to engage the said teeth of the saidtoothed bar and the said lever seating in the slot in the handle.

Q. A wrench comprising a shank, a removable jaw fixed on one end of theshank, a handle secured upon the other end or' the shank, a movable jawmounted on the shank, a toothed bar arranged in a recess in the shank, ascrew arranged in a recess in the shank below said toothed bar, a guideplate attached to the shank and extending in front of said screw andover a portion of the toothed bar, and a lever pivotally attached to thesliding jaw and having a tooth engaging said toothed bar.
